Abstract

Environmental monitoring analysis were analyzed for the period from 1988 to 2007 near King Sejong Station. Extreme environment structure behaviors(Marine Biology Lab.) were evaluated using monitoring sensors developed commercial sensors. Also when installing the sensors ambient environment of the King Sejong Station, to analyze the measured data and the comparative behavior of the structure were analyzed. As a environmental monitoring analysis result at King Sejong Station temperature, sensors were installed to withstand about $-25.6^{\circ}C$ or less and 49.5m/s. They were needed that the height of 225.0cm or more to be installed during the installation. For several monitoring sensors used in Antarctic, temperature, snow and strong winds were very sensitive to the atmospheric environment. Quite often a camouflage(animals and humans) would make it necessary to provide housing for monitoring sensors. Therefore, protection system developed for these sensors were to protect the sensors and data logger. Protection system the newly developed, is economical, easy to install even in harsh environments. Based on the measurement result of the one year, consider electrode applicability of the protection system, it was confirmed that the behavior of the structure is also predictable.

극한환경에서의 구조물 거동을 파악하기 위하여 남극 세종과학기지 부근의 기상환경을 분석(1988년-2007년 및 2010년)하고, 이에 적합한 상용화된 계측기를 선정하여 남극기지(생물해양연구동)에 설치하여 검토하였다. 남극 세종과학기지 기상환경분석결과, $-25.6^{\circ}C$ 이하의 온도 및 49.5m/s정도의 바람에도 견딜 수 있는 계측기를 설치해야 하며 설치위치도 지표면에서 225.0cm 이상이어야 한다. 또한, 남극에서 사용할 계측기 센서의 경우 온도, 폭설 및 강풍에 민감하고, 기상환경 이외에 남극의 동물이 침범할 수 있으므로 계측기 및 계측기용 데이터로거를 보호할 수 있는 시스템을 개발하여 적용하였다. 새롭게 개발된 보호시스템은 극한환경에서도 설치가 용이하고 경제적이다. 1년간의 계측결과를 바탕으로 보호시스템의 극지 적용가능성을 검토하였으며, 구조물 거동도 예측이 가능함을 확인하였다.
